I have a use case where I want ID3 metadata for a live stream to arrive a few seconds ahead of the video event which it aligns with. I think I can accomplish this if I delay a live input stream and then inject metadata into the **delayed** stream.

I am able to successfully do both of these things independently, but can’t seem to inject metadata into the **delayed** stream.

I used this example to successfully inject metadata into a normal stream:

I used this example to successfully delay a stream:

These both work on their own, but if I try to inject metadata into the delayed stream, the **LiveStreamPacketizerDataHandler.onFillChunkDataPacket()** event never fires, however I see the delayed stream exists when I call the Java module.

For example I have “myStream” and “myStream\_delay” which is delayed by 10 seconds. FYI, the delayed stream is a copy of an incoming RTMP stream and created via Java code, it is not a “normal” stream…

Injecting metadata into “myStream” works fine, and that data even appears in “myStream\_delay”…However, I want the data to be injected about 10 seconds **ahead** of the video stream. When I try to inject metadata into “myStream\_delay”, the module function LiveStreamPacketizerDataHandler.onFillChunkDataPacket() never gets called. Do I have to do something special to register a listener on the delayed stream?
